SOMERSET TWP MUN AUTH LISTIE Water System

Consumer Confidence Report status

SOMERSET TWP MUN AUTH LISTIE must publish a Consumer Confidence Report — the annual drinking water quality report covering calendar year 2026 — by July 1, 2027.

As of August 1, 2026, EPA's federal records show no open violations for SOMERSET TWP MUN AUTH LISTIE.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026.

SOMERSET TWP MUN AUTH LISTIE is one of 3,064 community water systems in Pennsylvania in the 500 or fewer people size category, serving 218 people from groundwater.

As of August 1, 2026, its federal record holds 129 entries between 1976 and 2024, all of which EPA lists as closed.

Of the 129, 127 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves volatile organic chemicals, inorganic chemicals, and synthetic organic chemicals.

When is SOMERSET TWP MUN AUTH LISTIE’s next Consumer Confidence Report due?

SOMERSET TWP MUN AUTH LISTIE’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

What is a Consumer Confidence Report?

A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
